Answer:
a. Slant asymptote with a slope of 5
Step-by-step explanation:
Dividing out the polynomials, you get ...
[tex]\dfrac{5x^2-x+13}{x+10}=5x-51+\dfrac{523}{x+10}[/tex]
As the magnitude of x gets large, the fraction goes to zero, and the behavior matches the line ...
y = 5x -51
This is a slant asymptote with a slope of 5 and a non-zero y-intercept.
